Add a function pointer to raid_bdev_module to be called before the bdev
is registered and a corresponding one to be called before the bdev is
unregistered. This allows setting up the bdev parameters and any custom
initialization/cleanup required for the raid module.

Pass raid_io instead of bdev_io to raid_bdev_queue_io_wait() and its
callbacks to eliminate unnecessary type conversions. Pass bdev and
io_channel directly as parameters instead of passing a base device
index.

Don't pass the error code to the function and instead move the -ENOMEM
check to the callers where it makes more sense.

This will make it easier to get to the raid_bdev when we only have the

The original io channel is not used directly, only its context (struct
raid_bdev_io_channel) which contains member bdevs' io channels. Store it
directly in raid_bdev_io to eliminate conversions.

Add the ability to register RAID modules. Supported RAID levels are
determined based on the list of registered modules.
The module descriptor structure will hold the function pointers for
RAID-level specific operations.
